Container House Wall Structure

The walls of container houses typically use sandwich-structured thermal insulation sandwich panels, composed of inner and outer metal panels with thermal insulation material filled in between, offering thermal insulation, sound insulation, fire resistance, and structural stability.

Wall Materials and Structure

The core of container house walls is the thermal insulation sandwich panel. Its inner and outer layers often use galvanized steel sheets or color-coated steel sheets, which are corrosion-resistant and have high strength. The thermal insulation material filled in the middle is usually rock wool, glass wool, or polyurethane foam. These materials have low thermal conductivity and can effectively block heat transfer. For example, a 100mm-thick composite wall can have thermal insulation performance comparable to that of a 610mm-thick traditional brick-and-concrete structure wall, significantly improving winter warmth retention and summer heat insulation. Additionally, the sandwich panel structure uses an integrated molding process to tightly combine the insulation layer with the panels, avoiding the issue of insulation material separation from the wall in traditional construction and further enhancing thermal insulation performance.

Functional Characteristics

1. Thermal Insulation and Sound Insulation: The thermal insulation material in the sandwich panel reduces heat conduction by blocking air flow, while the density of the metal panels can effectively absorb and reflect sound waves, reducing external noise interference.
2. Fire Resistance: Inorganic thermal insulation materials such as rock wool and glass wool are non-combustible. Polyurethane foam can also reach the B1 fire resistance standard after flame-retardant treatment, meeting building safety requirements.
3. Structural Stability: The wall is fixed to the steel frame with connectors, forming an integrated load-bearing system that can withstand external loads such as wind pressure and snow load, avoiding the deformation issues common in single-layer iron sheet structures.

Construction and Customization

Wall modules are prefabricated in the factory and quickly connected to the base and roof on-site using bolts or welding, shortening the construction period. Users can customize the wall color, window and door positions, and interior decoration according to their needs, such as adding sound insulation cotton, decorative panels, or integrated circuit systems to improve living comfort. Some high-end products also adopt a double-layer sandwich panel design to further enhance thermal insulation and sound insulation effects.
